With a height of 14.5 feet and a length of 316 feet, the dam provides a storage capacity of 990 acre-feet and covers a surface area of 73 acres. Despite its age, the dam is in satisfactory condition according to the last inspection conducted in October 2021.
Managed by a private owner, the dam is regulated by the New Jersey Department of Environmental Protection (NJDEP) and undergoes regular inspections to ensure its safety and functionality. With a high hazard potential due to its location on the Post Brook, the dam is designed to withstand up to 19 cubic feet per second of maximum discharge. While no spillway information is provided, the dam's emergency action plan (EAP) was last revised in February 2013, indicating a commitment to emergency preparedness.
The Congressional District 11 representative, Mikie Sherrill (D), oversees Post Brook Dam within the Philadelphia District of the US Army Corps of Engineers. Water resource and climate enthusiasts interested in the management and maintenance of dams will find Post Brook Dam to be a fascinating case study of historic infrastructure serving both recreational and water management purposes in Passaic County, New Jersey.
